Jiang Chen, who planned to repeat his studies, signed up for a physics summer system class with a well-known domestic learning software during the summer vacation. He casually joined the penguin group specially formed in this system class. When Jiang Chen was planning to dive until the end of the course, he met the teaching assistant who was solving problems online. My little brother is very good at physics. There is no question he can't answer. He is very popular. Jiang Chen, who is obsessed with physics, chatted privately for advice. Well, my little brother has a nice voice and he is a nice person. I want to get along with him. Note: ① A short essay ③ There is no outline, just write whatever comes to mind ④ I'm not sure about the attack or the response, it's just a story about two young brothers falling in love online, see if you like it
